摘要

Although body centered cubic (BCC) light weight high entropy alloy (LWHEA) has high specific strength, its uniform deformation ability is poor, which restricts its engineering application. This study investigated the effect of heat treatment on the grain refinement and tensile property of hot-forged TiZrVNbAl LWHEA. The as-forged sample occurred partly recrystallization at grain boundaries because of relative high strain rate. Fully recrystallized grains with the size of ~45 μm were obtained after annealing at 750℃ for 1 h, and the grain size will increase when annealing temperature increased further. Compared with the as-forged sample, the uniform elongation of samples annealed at 750℃ for 1 h increased from 3% to 15%. The above results could be a good reference for the mechanical property improvement of hot forged LWHEA.
